A business must choose between three alternatives that each have a 5-year life. Alternative X has a cost of $611 and annual benefit of $159. Alternative Y has a cost of $498 and annual benefit of $138. Alternative Z has a cost of $211 and annual benefit of $69. Assume the MARR is 8.000% and use annual benefit-cost ratio analysis. Which alternative should the business select? What was the last incremental B/C ratio you used to make the selection? Give ratio to 3 decimal places, like 0.954 or 1.761
